Help with .htaccess

Hi all

I require some help with .htaccess on dynamic urls thought I'd worked it out then when I tried it I had failed miserably.

What I have at present is a url which ends

?Keyword=<span style="colorrange;">searchterm</span>

I would like it to read

<span style="colorrange;">seachterm.html</span>

If this is possible can some kind person please post the required script.

I'm not too hot on .htaccess, but the following should work ok, assuming you have mod_rewrite running.

 RewriteEngine On
RewriteRule ^(.*)\.html$ /path/to/search/script.php?keyword=$1

Hope it helps
